Study hybrid Treatment Technologies using (MBBR with Electro-flotation) for Textile wastewater

Abstract

A novel hybrid approach to the global development treatment technology was introduced in this research, by using two sustainable green technologies treatment methods as (MBBR) combined with the Electro-flotation process. To improve the removal efficiencies of persistent and non-biodegradable dissolved organic dyes (Methylene blue dye) by using Iron and Aluminum electrodes. The treatment system achieved high performance than that any single treatment process and without the need to add chemical reagents. The characteristics of wastewater from textile dyeing used in this study were simulated to the General Establishment of Cotton Textile Industry / Baghdad. In addition, one of the most sustainable and useful byproducts is found to be producing H2 gas at a rate of 1:13L. As a result, in the continuous system the optimum removal efficiencies of color, COD, and BOD are 90.08%, 100%, 100% respectively, were achieved at (200V, 2cm electrodes distance, 5 minutes, pH=7, 8 number of electrodes, 30gm weight of media).
